EXCAVATING-MAGHINE.

T0 all'whom it may concern.-

Be it known that I, CLAUDE Er Nnennr,

a citizen of the United States, residing at that type of excavating machine shown in my Patent No. 1,053,428. The object of my present invention is to provide means to enable the excavator bucket. to' be dumped upon the rearward. travel of the-bucket along the supporting cable as well as 'upon the forward travel thereof under the pulling action of the load line.

IVith this end in View my invention is embodied in preferable form in the device hereinafter described and illustrated in the accompanying drawings.

In these drawings, Figure 1 is a side viewin elevation of an excavator bucket and'carrier showing the same mounted upon a slack cable; Fig. 2, is a front View in elevation and Fig. 3 is a rear view in elevation.

Referring to the drawings, 1 indicates a track cable of what is known as the slack type by means of which the bucket and its carrier may be raised and lowered to and from a bed of-material to be excavated and along which the carrier is adapted to be drawn to move a loaded bucket from an excavating point to the point of discharge. A

load line 2 is provided with an upper branch 3 and a lower branch 4, both of which are connected separately to an. excavating bucket 5 and by means of which load line the bucket is drawn up into engagement with its latching means on .the carrier and the carrier and bucket are drawn along the bed of material to be excavated and therefrom to the point of discharge The lower branch 4 of the load line ,is connected directly to the lower front part of the bucket while the upper branch 3 runs over a pulley 6 which is mounted upon a front arm 7 of a bucketcarrier 8. Theend of the branch 3 is connected to a cross arm 9 extending trans- 'versely of the bucket andsecured to the side walls thereof at their upper edges.

Onthe pivot pin 10 on which the pulley 6 is mounted, is pivoted a rigid latch mem- Specification of Eettcrs Patent. Application filed May 10, 1913. Serial No. 766,723.

ber 11, the lower hook portion 12- of which rammed reb. 3,1914.

is of sufficient weight to car..- the hook to normally swing rearwardly, so that it will engage the under side of a cross bail 13 fastened to the upper edges of the bucket near the front end of the latter. This latch hook serves asthe meansfor holding the bucket in load position and keeping it parallel with the carrier. The upper end of the latch member has a forked arm 15 adapted to embrace theload' cable and this arm is adapted to strike against a trip member 16 fixed on the main cable 1 adjacent to the point of discharge. Such point of discharge is usually located between the point ofrexcavation and the location of the power means, such as the hoisting engine, and the bucket is drawnv along the'slack cable up to this point of discharge by means of power applied to the load line, and when the upper arm of the latch hook contacts with. the

trip on the supporting cable, the hook is thereby automatically released from the bucket and at the same time the load line is also slackened by the operator, whereupun the bucketwill be dumped. v

The bucket carrier consists at a rigid, open, vertical frame andv on the rear vertical arms of this frame the bucket piv-'- oted by means of a connecting bail i7.

Extending rearwardly and slightly.up-

wardly from the upper horizontalvarms of i thecarrier frame, are parallel extension members 18. provided with a series of holes 19 through any of the corresponding pairs of which holes is adapted to be inserted a supportingbolt 20 on which is pivoted the side arms of a forked member or bail 21, which is open at its upper end and closed at the lower end.

Each of these members is This open bail surrounds the supporting cable and the vertical arms thereof are adapted to strike against a trip block 22 which is fixed on the said cable at a point on the far side of the excavating bed.

A transverse bolt 23 connects the two arms of the bail member at their upper ends and pivotally connecting this bolt and a similar bolt'24 mounted in the upper ends of the two members of the forkedarm 15 of the latch member 11, is a rod 25. By the above arrangement it will be seen that when the carrier is permitted to travel along the supporting cable to a point where thebail. 21 will contact with the trip block 22.-thatsuch bail will be rocked on the bolt 20, thus drawing rearwardly the rod 25 and rock-' w the hook troni engage e bucket and. permit the latter roped rroni the iront end oi the letter on either side oi the bed of material being er;-

cavated, which. arrangement permits the operator to select either the or near side as the point of discharge for the material to he recovered and also provides the advan tage of enabling the operator to excavate, prelimin. ril to the main operation, a few loads of Waste material from the top of the bed, such as sediment, dirt, etc, until the clean gravel is reached, the sediment or waste material being discharged on the far side of the bed and the material to be recovered being pulled toward the hoisting englue and discharged on the near side.

Having thus described ny invention What 1' claim 1. in an excavating apparatus in combination with a track cable a bucket carrier mounted on said track cable,a bucket pivoted on said carrier, a load cable, means to hold said bucket in load carrying position and means operable to trip said holding means upon the travel of the bucket carrier in either direction on the track cable, substantially as described.

2. In an exce iting apparatus, in cou bh nation with a track cable, a bucket carrier .inouuted on said track cable, a bucket-pivoted on said carrier and operableto dump at its front end, latching; Ineans'i'or the bucket and mmns to trip said latching moans upon the backward travel oi the bucket on the track fable, substantially as i'lescribed.

3. In an excavating apparatus in combination vi-L. a track cable, a bucket carrier mounted on said cable, a bucket pivoted on said carrier and operable to discharge from its front end, a load cable, latching nieans to hold the bucket in load carrying position, trip means for said latching means lo rated on the track cable intermediate the point of excavation and, the point of applii on its ivot 10 so as l cation. of power to the load line means located. on the track cable on other side of said point of excavation, sunstantially as described.

4:. In an excavating apparatus, in combination With a track cable, a bucket carrier mounted on said cable, a bucket pivoted on said carrier and operable to discharge at its front end, latch means mounted on the carrier near the front end thereof and engaging said bucket, connected latch tripping means opposite ends of the carrier and trip blocks on said track cable operable to engage and trip the respective tripping means, substantially as described.
